IRIDAS has become a key component of our edit and finishing solution. Once the 2D edit has been locked on each reel of the film, the editor exports an EDL for SpeedGrade, which then directly accesses the final rendered frames of the film.

Once conformed within SpeedGrade, the stereography department steps in. Their roll includes confirming that all final frames are 100% accurate between eyes as any slight disparities can cause visual artifacts and discomfort when viewing 3D films. They then apply any Depth Blending effects required and the application of floating windows is the final pass. SpeedGrade NX is the last step before going to DCI conversion either for cinema tests or final exports of the film. Effectively SpeedGrade was the solution to all our stereoscopic editing and DI needs. It has also given us the potential to do some primary grade work on the film before sending it out for the final grade.


SpeedGrade certainly filled all our current pipeline requirements with regards to a stereoscopic DI solution. Its near-perfect importing of EDLs which then link directly to the DPX sequences has made it so simple going from the offline edit to SpeedGrade. The flexibility and openness of SpeedGrade’s storage format (XML) has allowed us to write add on tools for some smaller in house requirements. The customization via the .fcps files has also made SpeedGrade fit perfectly into our pipeline.

Once we got our heads around the methodologies and innovations of IRIDAS and SpeedGrade, it became an indispensable tool in our arsenal and an extremely powerful stereoscopic workflow enhancement that has become second nature to our team.
